Context values
Some unit families need one extra value for a physically accurate result.
Use the converter to see the formula.
mmHg and Metric horsepower measure different quantities, so no single result applies.

Formula
mmHg (mmHg) measures pressure and mechanical stress, while Metric horsepower (PS) measures power. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
mmHg relates to its own pressure and mechanical stress base unit by a factor of 133.322. PS relates to its own power base unit by a factor of 735.499.

Frequently asked questions
Can mmHg be converted to Metric horsepower?
Not directly. mmHg measures pressure and mechanical stress and Metric horsepower measures power. Converting between different physical quantities needs an extra physical relationship (such as area, distance, or time), not just a unit ratio.
What is mmHg used for?
The mmHg (mmHg) is a unit of pressure and mechanical stress. Millimeters of mercury at standard gravity.
What is Metric horsepower used for?
The Metric horsepower (PS) is a unit of power. Metric horsepower.
Why does the converter show an incompatible units message?
The Universal Converter only calculates a numeric result when both units share the same physical dimension. Since mmHg and Metric horsepower don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert mmHg to instead?
Use another pressure and mechanical stress unit, such as one of the related mmHg conversions linked below.
What should I convert Metric horsepower to instead?
Use another power unit, such as one of the related Metric horsepower conversions linked below.

About this conversion
This page compares mmHg (mmHg) and Metric horsepower (PS) within the engineering converter.
Millimeters of mercury at standard gravity. Metric horsepower.
Because mmHg measures pressure and mechanical stress and Metric horsepower measures power, the two units are not directly convertible: there is no fixed ratio that turns one into the other without additional information.
The calculator above will report that these units are not compatible. For a working result, choose two units from the same measurement family — see the related conversions below.
